Description

Technical Field

[0001] This invention relates to the field of plastic pallet processing, and in particular to a flipping device for the process of installing rubber feet on plastic pallets. Background Technology

[0002] A plastic pallet is a type of pallet used for storing, transporting, and stacking goods. It is made of plastic. Plastic pallets are typically made from high-strength, durable plastic materials and are lightweight, waterproof, corrosion-resistant, and easy to clean. They are widely used in the logistics industry, replacing traditional wooden or metal pallets. They are widely used in warehousing, logistics, and manufacturing industries for loading and transporting various goods, such as food, beverages, chemicals, and electronic products.

[0003] After the plastic pallet is manufactured, rubber feet need to be installed on its bottom. The installation of rubber feet allows the surface of the plastic pallet to directly contact the bottom surface, avoiding wear and tear on the bottom surface of the plastic pallet during use.

[0004] Currently, the installation of rubber feet on the bottom of plastic pallets is generally done manually. Workers need to manually flip the plastic pallet and then use a rubber mallet to hammer the rubber feet into the rubber foot mounting grooves on the bottom of the plastic pallet one by one. The overall processing procedure is labor-intensive, resulting in high labor costs. Therefore, further improvements and optimizations are needed. Summary of the Invention

[0041] Please see Figures 1 to 10 The present invention provides a technical solution: a flipping device for installing rubber feet on a plastic pallet, comprising a frame 1, a flipping component 2 movably disposed in the middle of the frame 1, the flipping component 2 being a rectangular plate-shaped component, the flipping component 2 being used to drive the plastic pallet to flip, a central shaft component 3 movably disposed inside the flipping component 2, the central shaft component 3 being designed to facilitate the rotation of the flipping component 2, an assist groove being disposed inside the flipping component 2 corresponding to the central shaft component 3, the assist groove being a horizontal columnar groove, the horizontal dimension of the assist groove being smaller than the width of the flipping component 2, a vortex elastic component 4 being fixedly installed inside the assist groove, the other end of the vortex elastic component 4 being fixedly connected to the central shaft component 3, the vortex elastic component 4 being used to assist when the flipping component 2 needs to flip back, so that the flipping component 2 can quickly rotate back;

[0042] First, place frame 1 on the plastic pallet production line, and align flipper 2 with the plastic pallet on the production line.

[0043] Vertical rods 5 are provided on both sides of the flipping component 2. Each vertical rod 5 is a vertical column-shaped member, and its height is adapted to the frame 1. The upper end of each vertical rod 5 is fixedly connected to the outside of the frame 1. A rotating groove 6 is provided inside each vertical rod 5, and the rotating groove 6 is a vertical rod-shaped groove. One side of the rotating groove 6 passes through the vertical rod 5. A movable component 7 is sleeved on the outer side of the middle part of the vertical rod 5. The rotating groove 6 is used for the vertical movement of the movable component 7. The movable component 7 is a block-shaped member with a mountain-shaped cross-section. The size of the middle vertical block of the movable component 7 is adapted to the rotating groove 6. Several middle blocks of the movable component 7 are located inside the rotating groove 6. The movable component 7 is positioned on both sides... The movable part 7 is located on the outside of the vertical rod 5 and is attached to the vertical rod 5. The side of the movable part 7 that is close to the flipping part 2 is fixedly connected to the central shaft 3. When the movable part 7 moves, it drives the flipping part 2 to move upward through the central shaft 3. The movable part 7 is screwed with a rotating part 8. The rotating part 8 is set as a vertical lead screw. The rotating part 8 is used to drive the movable part 7 to move upward. The bottom of the rotating part 8 is movably connected to the vertical rod 5. The upper end of the rotating part 8 passes through the vertical rod 5 and extends to the outside. A servo motor is fixedly connected to the upper end of the rotating part 8. The servo motor is fixedly installed on the upper end of the vertical rod 5. The servo motor is used to drive the rotating part 8 to rotate.

[0044] The servo motor drives the rotating part 8 through its output end. The rotating part 8 is screwed to the moving part 7, causing the moving part 7 to move along the rotating groove 6. The moving part 7 drives the flipping part 2 to move through the central shaft part 3.

[0045] Because the plastic pallet needs to be limited and fixed before it can be flipped, multiple sets of push-down parts 9 are provided at the bottom of the flipping part 2. The push-down parts 9 are vertical rod-shaped parts, and each push-down part 9 has a sliding groove 10 inside. The sliding groove 10 is a vertical groove, and an extrusion part 11 is movably arranged inside the sliding groove 10. A push rod 12 is fixedly connected to the upper end of the extrusion part 11. The push rod 12 is a vertical column-shaped part. The push rod 12 is used to push the extrusion part 11 down along the sliding groove 10. The upper end of the push rod 12 passes through the push-down part 9 and is fixedly connected to the bottom of the flipping part 2. A push-down elastic part 13 is sleeved on the outside of the push rod 12. The bottom of the push-down elastic part 13 is fixedly connected to the outside of the push-down part 9. The push-down elastic part 13 is used to reset the push-down part 9 after the flipping part is completed.

[0046] A shrinking elastic element 14 is provided at the bottom of the transfer groove 10. The shrinking elastic element 14 is a transverse elastic element. Limiting elements 15 are fixedly connected to both sides of the shrinking elastic element 14. The shrinking elastic element 14 is used to shrink the limiting elements 15 inward. The limiting elements 15 are plate-shaped. An outward pushing element 16 is fixedly connected to the upper end of the limiting elements 15. The outward pushing element 16 is a transverse block-shaped element. The limiting elements 15 are used to limit the outward pushing element 16 and prevent the outward pushing element 16 from leaving the transfer groove 10. The upper inner side of the outward pushing element 16 is set as an inclined surface. The bottom ends of the extrusion element 11 are provided with rounded corners corresponding to the outward pushing element 16. When the extrusion element 11 moves down, it rubs against the inclined surface of the outward pushing element 16 through the rounded corners, pushing the outward pushing element 16 to expand outward. An adhesive pad 17 is installed on the inner end of the outward pushing element 16. The adhesive pad 17 is set as The rubber gasket and the fitting pad 17 are used to increase the friction between the extrusion part 11 and the pusher part 16, so that the extrusion part 11 is limited. The elastic force of the pusher elastic part 13 is greater than the friction limiting coefficient of the fitting pad 17. The outer side of the pusher part 16 passes through the pusher part 9 and extends to the outside. The outer side of the pusher part 16 is fixedly connected to the plug 18. The plug 18 is set as a vertical rod. The plug 18 is used to insert into the grid of the plastic tray. At the same time, it limits the plastic tray when the pusher part 16 expands outward. The size of the plug 18 is smaller than the grid size of the plastic tray. The outer side of the plug 18 is fixedly installed with the limiting adsorption part 19. The limiting adsorption part 19 can improve the fixing effect between the plug 18 and the plastic tray by adsorbing itself with the inner wall of the plastic tray grid, so as to prevent the plastic tray from falling off when flipping.

[0047] When the flipper 2 moves down, it pushes the push rod 12 to move the pusher 9 down. When the bottom of the pusher 9 is in contact with the top of the plastic tray, the insert 18 is inserted into the grid of the plastic tray. At the same time, the flipper 2 continues to move down. The flipper 2 presses the extrusion member 11 down through the push rod 12. The extrusion member 11 causes the insert 18 to expand outward through the friction between its bottom end and the inclined surface of the outer pusher 16. The insert 18 limits and fixes the plastic tray by expanding outward. At the same time, the insert 18 presses the limiting adsorption member 19. The limiting adsorption member 19 further improves the fixing effect of the plastic tray by adsorbing onto the inner wall of the plastic tray grid.

[0048] To facilitate the flipping of the flipper 2 and the flipping of the plastic pallet, side members 20 are fixedly installed on the side of the vertical rod 5 away from the rotating groove 6. An auxiliary flipping shaft 21 is fixedly connected to the inner side of each side member 20. The auxiliary flipping shaft 21 is a horizontal rod-shaped member located on the upper side of the flipper 2. The auxiliary flipping shaft 21 is used to press the flipper 2 when the plastic pallet is moved upwards after the flipper 2 is fixed, causing the flipper 2 to rotate around the central shaft 3. A flipping limiting groove 22 is provided inside the flipper 2 corresponding to the auxiliary flipping shaft 21. The slot 22 is a transverse slot with a semi-circular cross section. A flipping limiting member 23 is movably installed inside the flipping limiting slot 22. The flipping limiting member 23 is located on the side of the flipping limiting slot 22 near the flipping shaft 21. Both ends of the flipping limiting member 23 are fixedly connected to the moving member 7. The flipping limiting slot 22 and the flipping limiting member 23 are mainly used to limit the flipping member 2 to prevent the flipping member 2 from flipping too much and to ensure the angle after the plastic pallet is flipped. At the same time, the flipping limiting member 23 can cooperate with the central shaft member 3 to limit the flipping member 2 after flipping.

[0049] Auxiliary components 24 are fixedly installed on both sides of the end of the flipping component 2 away from the auxiliary shaft 21. The auxiliary components 24 are columnar. A kit 25 is movably sleeved on the outside of the auxiliary components 24. The kit 25 is a ring sleeve. The upper end of the vertical rod 5 is provided with an auxiliary groove 39 corresponding to the auxiliary components 24. The auxiliary groove 39 is an inclined arc groove. The vertical rod 5 passes through both sides of the auxiliary groove 39. The size of the auxiliary groove 39 is larger than the diameter of the kit 25. When the auxiliary shaft 21 pushes the flipping component 2 to flip to a certain angle, the auxiliary component 24 is inserted into the auxiliary groove 39. The kit 25 moves along the auxiliary groove 39, so that the flipping component 2 flips at an angle greater than 90 degrees. The flipping component 2 can drive the plastic pallet to continue to flip by its own weight, so that the plastic pallet is flipped.

[0050] After the plastic pallet is flipped, rubber feet need to be installed. Therefore, a transmission wheel 26 is installed inside the upper part of the frame 1. The transmission wheel 26 is a pulley. One side of the transmission wheel 26 is connected to the drive wheel 27 via a belt. The drive wheel 27 is located on the upper part of a set of rotating parts 8. The drive wheel 27 is fixedly connected to the rotating parts 8. The rotation of the rotating parts 8 can drive the drive wheel 27 to rotate, thereby causing the transmission wheel 26 to rotate together. A transmission component 28 is fixedly connected to the bottom of the transmission wheel 26. The transmission component 28 is a disc-shaped component. Multiple sets of actuating plates 29 are fixedly connected in an annular shape on the outer side of the transmission component 28. The actuating plates 29 are all horizontal plate-shaped components. The transmission wheel 26 can drive the actuating plates 29 to rotate through the transmission component 28.

[0051] A toggle groove 30 is provided at the bottom of the toggle plate 29. The toggle groove 30 is an annular groove with a T-shaped cross-section. Inside the toggle groove 30, corresponding to the toggle plate 29, multiple sets of toggle members 31 are provided. Each toggle member 31 is an arc-shaped block with a T-shaped cross-section. The upper end of each toggle member 31 is fixedly connected to the toggle plate 29. Multiple sets of rubber feet 32 ​​are movably arranged inside the toggle groove 30. Each rubber foot 32 is a T-shaped rubber structure. The T-shaped groove design of the toggle groove 30, in conjunction with the rubber feet 32, can prevent the rubber feet 32 ​​from tipping over. The toggle members 31 can easily push the rubber feet 32. 2. The moving part 30 is equipped with multiple sets of falling grooves 33 corresponding to the rubber feet 32. The falling grooves 33 are set as vertical columnar grooves. The size of the falling grooves 33 is adapted to the size of the circular block at the top of the rubber feet 32. The rubber feet 32 ​​are set inside the falling grooves 33. The moving plates 29 are all located at the top of the falling grooves 33. The falling grooves 33 can facilitate the replenishment of rubber feet 32 ​​after the bottom rubber feet 32 ​​are installed. The top of the frame 1 is equipped with a cover plate 40. The cover plate 40 is aligned with the moving groove 30. The cover plate 40 can facilitate the replenishment of rubber feet 32 ​​in the moving groove 30.

[0052] After the plastic pallet is flipped over, its rubber foot inlay groove is aligned with the rubber foot 32. The rotating part 8 continues to push the plastic pallet upward through the moving part 7. When the rubber foot 32 begins to be inserted into the rubber foot inlay groove, the transmission wheel 26 drives the actuating part 31 to be located at the upper end of the drop groove 33 to limit the rubber foot 32. When the rubber foot 32 is inserted, the actuating part 31 leaves, and the subsequent rubber foot 32 falls from the drop groove 33.

[0053] A sluice gate 34 is provided at the bottom of the drop trough 33. Two sets of sluice gate components 35 are symmetrically arranged inside the sluice gate 34. Each sluice gate component 35 is a rectangular block and is used to limit the rubber feet 32 ​​inside the drop trough 33, preventing them from falling directly. A slot 36 is provided on the inner side of each sluice gate component 35 corresponding to the rubber feet 32. The size of the slot 36 is smaller than the size of the circular block at the top of the rubber feet 32. The slot 36 facilitates the limiting of the rubber feet 32. A through slot 36 is provided at the bottom of the rubber feet 32 ​​inside the drop trough 33. The groove 36 extends to the outside, and a fixed shaft 37 is movably provided inside one side of the opening and closing part 35. The fixed shaft 37 is fixedly connected to the side wall of the opening and closing groove 34 on both sides. One end of the torque elastic member 38 is fixedly connected to the outside of the fixed shaft 37, and the other end of the torque elastic member 38 is fixedly connected to the opening and closing part 35. Through the torque elastic member 38, it is easy for the plastic tray to open through the opening and closing part 35 after the rubber foot 32 is inserted into the rubber foot inlay groove, so that the plastic tray completes the installation of the rubber foot.

[0054] In use, the frame 1 is first placed at the top of the plastic pallet production line. When the plastic pallet is aligned with the flipping component 2, the servo motor is started. The output of the servo motor drives the rotating component 8 to drive the moving component 7 to move. The moving component 7 drives the flipping component 2 to move down through the central shaft component 3. The flipping component 2 pushes the lower push component 9 down to the top of the plastic pallet, so that the plug 18 is inserted into the grid of the plastic pallet. The rotating component 8 continues to drive the moving component 7 to push the flipping component 2 down. The flipping component 2 pushes the extrusion component 11 down along the transfer groove 10 through the push rod 12, so that the extrusion component 11 extrudes the inclined surface of the outer push component 16 through the bottom rounded corner, so that the plug 18 expands outward. The plastic pallet is limited by the expansion of the two sets of plugs 18. At the same time, the limiting adsorption component 19 on the outside of the plug 18 adsorbs to the inner wall of the plastic pallet grid for further fixation.

[0055] At this time, the servo motor reverses, and the rotating part 8 drives the flipping part 2 to move upward through the moving part 7. When the upper end of the flipping part 2 is in contact with the flipping shaft 21, the flipping shaft 21 squeezes the flipping part 2, causing the flipping part 2 to start flipping around the central shaft 3. After flipping to a certain angle, the flipping part 24 enters the flipping groove 39. The inner wall of the flipping groove 39 rubs against the kit 25, causing the flipping part 2 to rotate further. The flipping limit part 23 is positioned on the other side of the flipping limit groove 22 to limit the flipping part 2. At this time, the flipping part 2 drives the plastic tray to complete the flipping, so that the rubber foot inlay groove on the plastic tray is aligned with the rubber foot 32. At the same time, during the flipping process, the vortex elastic part 4 is squeezed and begins to contract.

[0056] At this time, the rotating component 8 drives the flipping component 2 to move upward. When the rubber foot insert on the plastic tray begins to contact the rubber foot 32, the driving wheel 27 drives the actuating plate 29 to the upper end of the drop groove 33 through the transmission wheel 26, so that the actuating component 31 is located at the upper end of the rubber foot 32 in the drop groove 33, squeezing the rubber foot 32 to prevent the rubber foot 32 from leaving the drop groove 33 when the plastic tray moves upward. After the rubber foot 32 is fully inserted into the rubber foot insert on the plastic tray, the servo motor reverses, and the plastic tray drives the rubber foot 32 to move downward. The rubber foot 32 squeezes the opening and closing component 35, causing the opening and closing component 35 to open. After the rubber foot 32 leaves, the torsion... The force elastic element 38 drives the opening and closing element 35 to close the opening and closing groove 34 through its own torque. At the same time, the actuating plate 29 drives the actuating element 31 to push the rubber foot 32 in the actuating groove 30 to move, so that the rubber foot 32 is replenished into the falling groove 33. When the flipping element 2 moves down and contacts the flipping shaft 21, the flipping element 2 rotates in the opposite direction. When the flipping element 2 rotates to a certain angle and the flipping shaft 21 can no longer be pushed, the vortex elastic element 4 drives the flipping element 2 to complete the final reversal process through its own torque, so that the plastic pallet is aligned with the production line. Then, with the help of manual labor, the plastic pallet is removed from the bottom of the flipping element 2 to complete the installation of the rubber foot.
